it's fine with us. sir, tell us, i assume this is a sir. i don't know. tell us what you can about what you would imagine given pictures you're see something. >> yes. the caveat is that i'm watching your broadcast on television. i'm not at the scene. but having had some experience in flammable liquid and flammable gas fires, it appears from your coverage that this would be fueled by some type of pressurized gas whether natural gas or propane. you see a lot of smoke coming off. that smoke is probably, again, probably, from exposure that's have been caught on fire from this fireball, one of the reasons these are challenging is because if you do have natural gas that is on fire and you put it out without stopping or controlling the flow of the gas, what do you do with these explosives?
